Myelopathy secondary to copper deficiency as a complication of treatment of Wilson's disease.

Wilson's Disease (WD) is an autosomal recessive disorder of copper metabolism resulting in a pathological accumulation of this metal, initially in the liver and later in other organs, mainly brain. Treatment with copper chelating agents and zinc salts results in a depletion of copper deposits and prevents or reverses the clinical manifestations. Copper deficiency may cause haematological and neurological changes, the latter principally being polyneuropathy and myelopathy.
